Optical kis tau tus mob
Txij li xyoo 2000, nrog rau kev txhim kho ntawm kev sib txuas lus thev naus laus zis, kev sib txuas lus fiber ntau tau tshwm sim optical module kis tau tus mob, thiab tom qab xyoo 2002, digital transmission HDMI audio thiab video teeb liab cov khoom kuj tau tshwm sim hauv cov khoom siv hluav taws xob.Thaum lub Plaub Hlis 2002, Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, Toshiba xya lub tuam txhab koom ua ke tsim lub koom haum HDMI high-txhais multimedia interface interface, HDMI kis tau tus mob yog muab faib ua high-ceev teeb liab kis tau tus mob thiab tsawg-ceev teeb liab kis tau tus mob ob feem. : 1-12 feet ntawm 12 4 khub ntawm cables xa cov teeb liab ceev, siv TMDS sib txawv signaling tshuab (TMDS (Lub Sijhawm Tsawg) tsim los ntawm Silicon Image Differential Signal) txo qis kev sib txawv ntawm cov teeb liab kis tau tus mob, TMDS yog lub teeb liab sib txawv, siv Qhov sib txawv kis tau tus mob, uas yog lub hauv paus ntsiab lus ntawm HDMI technology, nyob rau hauv optical fiber kis tau tus mob HDMI: cov 4 khub ntawm 12 TMDS cables yog kis los ntawm 4 VCSEL + 4 multimode optical fibers, uas yuav daws tau yooj yim cov teeb meem ntawm high-ceev kis tau tus mob.Hauv HDMI qis-ceev kis tau tus mob channel, 13-19 tus pins hauv HDMI muaj 7 cov khoom siv hluav taws xob: 5V fais fab mov, HPD hot-swap qhib CEC, internet, SDA, SCA, DDC raws.Qhov kev daws teeb meem tseem ceeb tshaj plaws nyeem DDC channel: nws yog cov lus txib ntawm I2C interface ntawm HDMI qhov los nyeem E-EDID ntawm qhov kawg tau txais.I2C, luv luv rau Integrated Circuit Bus, yog lub tsheb npav sib txuas lus uas siv ntau tus tswv-tus qhev architecture.Tus thawj coj ntawm I2C kuj yog ib tus tsim ntawm lub koom haum HDMI: Philips Semiconductors.
HDMI cables feem ntau yog siv los txuas cov khoom siv suab paj nruag rau TVs thiab cov saib, yog li feem ntau ntawm lawv yog qhov luv luv, feem ntau tsuas yog 3 meters ntev;Cov neeg siv yuav tsum ua li cas yog tias lawv xav tau ntau dua 3 meters?Yog tias koj txuas ntxiv siv tooj liab hlau, txoj kab uas hla ntawm tooj liab yuav loj dua, nws yuav nyuaj rau khoov, thiab tus nqi yuav siab.Yog li ntawd, txoj kev zoo tshaj plaws yog siv cov fibers optical.HDMI AOC optical hybrid cable khoom yog qhov khoom ntawm kev cuam tshuam kev sib raug zoo, lub hom phiaj tseem ceeb hauv kev txhim kho yuav tsum yog tias tag nrho HDMI 19 cables yog optical fiber ntau kis tau tus mob, uas yog qhov tseeb kho qhov muag fiber ntau kis tau tus mob HDMI, tab sis vim hais tias 7 cables ntawm cov qis- ceev channel siv VCSEL + multimode fiber ntau lub teeb liab qis ceev encoding thiab kev txiav txim siab yog qhov nyuaj dua, tsuas yog tus tsim tawm tsuas yog cov teeb liab siab ceev hauv 4 khub ntawm TMDS raws rau VCSEL + multimode fiber ntau kis tau tus mob, qhov seem 7 cov xov hlau hluav taws xob tseem txuas ncaj qha los ntawm tooj liab. wireIt tau pom tias tom qab lub teeb liab ceev tau xa los ntawm optical fiber ntau, vim qhov txuas ntxiv ntawm TMDS teeb liab kis tau tus mob, qhov kho qhov muag fiber ntau HDMI AOC tuaj yeem xa mus rau 100 meters lossis ntev dua.Optical fiber ntau HDMI AOC hybrid cable vim hais tias lub teeb liab qis tseem siv tooj liab xaim, qhov teeb meem ntawm kev kub ceev teeb liab tau daws, thiab qhov teeb meem ntawm cov teeb liab qis qis tooj liab kis tau tus mob tseem tsis tau daws, yog li nws muaj ntau yam sib xws. teeb meem hauv kev sib kis mus ntev.Thiab tag nrho cov no tuaj yeem daws tau tag nrho yog tias HDMI siv txhua qhov kev daws teeb meem kho qhov muag.All-optical HDMI siv 6 fibers optical, 4 los xa cov high-speed TMDS channel signals, 2 xa HDMI low-speed signals, thiab lwm 5V fais fab mov yuav tsum tau nyob rau hauv lub RX zaub kawg li excitation voltage rau HPD kub plugging.Tom qab siv tag nrho cov kev daws teeb meem kho qhov muag, HDMI, kev kub ceev TMDS channel thiab qis-ceev DDC channel raug hloov mus rau kev sib kis ntawm fiber ntau, thiab kev sib kis tau zoo heev.
Kev them nyiaj yug rau raws tu qauv specifications
Txawm hais tias optical tooj liab hybrid kab tau tsa qhov tsis muaj kev sib kis ntawm cov teeb liab nyob deb mus rau qhov siab heev, tseem muaj cov thev naus laus zis uas daws tau tag nrho cov khoom siv tooj liab raws li tus neeg xyuas pib, uas yog, ntshiab optical fiber ntau HDMI 2.1 kab, HDMI 2.1 ntshiab optical active optical cable (AOC) siab ua raws li HDMI 2.1 tus qauv, cov teeb liab kis tau tus mob yog tag nrho cov siv fiber ntau optical, tsis muaj tooj liab hlau, optical fiber kis tau tus mob tsis raug electromagnetic cuam tshuam.AOC kis tau tus mob teeb liab yog uncompressed, lub siab tshaj plaws bandwidth yog 48Gbps, muaj peev xwm xa tau zoo kawg nkaus 8K ultra-siab-txhais duab, qhov ntev tshaj plaws kis tau tus mob nyob deb ntawm 500m.Piv nrog rau cov xov tooj tooj liab, qhov fiber ntau optic cable no ntev dua, softer, sib dua, nrog cov teeb liab zoo dua thiab zoo meej electromagnetic compatibility yam ntxwv.Thaum pib ntawm lub xyoo, lub koom haum HDMI rau HDMI Cable certification xeem specifications rau ib tug loj hloov tshiab, tshiab DMI Passive Adapter ntawv pov thawj txoj kev npaj, yav dhau los nyob rau hauv lub Ultra High Speed HDMI Cable xeem specifications, ntxiv rau yuav tsum txhawb HEAC muaj nuj nqi, cov cable siv los xa HEAC tseem xav tau siv tooj liab xaim kom tau ntawv pov thawj, yog tias nws siv cov fiber ntau kho qhov muag, nws tsis tuaj yeem lees paub, thiab hwm High Speed HDMI HEAC muaj nuj nqi nyob rau hauv cov lus qhia cable yog xaiv tau, tom qab qhov kev hloov tshiab no tau dhau los ua Thawj qhov kev xaiv rau cov qauv kev sim ntawm tag nrho-fiber AOC Cable nyob rau theem no, ntshiab fiber ntau HDMI thaum kawg tau lees paub, tam sim no nws tau hais tias HDMI fiber ntau kis tau tus mob hauv optical hybrid cable (AOC) thiab tag nrho-optical kis tau tus mob zoo dua, qhov tseeb, feem ntau yog nyob ntawm tus nqi kev ua tau zoo thiab daim ntawv thov kev lag luam los txiav txim siab, txhua tus muaj nws tus kheej zoo
